Anno XXIV - n.4 - ottobre/dicembre 1991 Una misura didattica del flusso di energia radiante
In this article radiant energy flux is measured referring the temperature of a small blackened body to the temperature of a similar reflecting body. The reliability of the method is checked using electric lamps of different power output. Then the apparatus is used for measuring the efficiency of a solar cell, […]
Anno XXV - n.3 - luglio/settembre 1992 Una visione critica dell’attività pratica nell’insegnamento delle scienze sperimentali.
The article takes a critical look at practical work in school science and the often extravagant claims that we make for it. In asserting that much of what we do is ill-conceived, muddled and of little educational value, a case is made for a more rigorous, […]
Anno L - n.4 - ottobre/dicembre 2017 Un’espressione analitica per la costante di Wien
With the help of Planck’s formula for the black body radiation, it is possible to deduce Wien’s and Stefan-Boltzmann’s laws by means of the usual mathematical methods of secondary school. In particular, we can obtain an excellent approximation of Wien’s constant in terms of the physical constants h, […]
Anno XXVI - n.3 - luglio/settembre 1993 Uno strumento di valutazione né aperto né chiuso.
After a brief review of the problems connected with the use of open and closed tests, we present an instrument we developed (using some ideas of the APU project) where an almost completely open response is translated into dichotomous keys, suitable for computer processing. […]
Anno XXVII - n.1 - gennaio/marzo 1994 Uno strumento per gli insegnanti di scienze in formazione basato sulle percezioni degli studenti (Traduzione da School Science Review, sett. 89, 71(254), a cura di Nicoletta Lupino)
The article reports a research, based on a questionnaire answered by secondary school students in Kuwait concerning science classes. The aim of the research was to give feedback to training teachers about their behaviour in the classroom, as perceived by their students. […]
Anno XXVIII - n.2 - aprile/giugno 1995 Uso di simulazioni per studiare il moto browniano
After a brief historical introduction to Brownian motion, attention is given to the importance of this kind of motion when teaching about atomic structure of matter. Direct demonstrations in the school are difficult to show in a satisfactory and meaningful way, […]
Anno XLIV - n.2 - aprile/giugno 2011 Video ad uso degli studenti di fisica
Communication technologies allow teachers to keep in touch with their pupils in case of absence and after school hours. […]
Anno XXXII - n.2 - aprile/giugno 1999 Visita all’osservatorio astronomico
Visiting the astronomical observatory is the occasion of a cultural growth. This visit, to be effective and incisive, must be prepared, before and during the course of it, by dealing with some basic contents. These should be selected according to a triple reference: the pupils’ […]
